Etymology: – The generic name is a tribute to Dr. Neli Kika Honda, who has dedicated her scientific career to study the chemistry of the lichens from Mato Grosso do Sul since 1992 (Oliva et al. 1992).
Thallus foliose, medium-sized (3–5 cm across), homoiomerous, black to dark olive brown when dry (Fig. 3A, B, C); lobes irregular in outline, irregularly branched, 1.5–3.0 mm wide, plane; lobe surface plane and with longitudinal ridges when dry, not swollen; cortex with amorphous layer without euparaplectenchymatous cells (Fig. 3D); isidia granular, laminal, marginal, and on the margin of apothecia, simple to grouped; tomentum not observed.
